Specification of Letters Patent.

Patented July 4L, 1922;

Application filed November l5, 1920. Serial No. 424,295.

To all whom it may concern.'

Be it known that l, FRANK HAMAQHEK, a citizen of the United Statesn and resident Yof Kewaunee, in the county of Kewaunee and State of Viifisconsin, have invented new and useful Improvements in Green-Pea Viners, of which the following is a description, reference being had to the accompanying drawings7 which are a part of this speci tication.

This invention relates to green pea viners and has for its object to provide a covering for working parts to prevent peas being damaged thereby.

Green pea viners as usually constructed have rotating separating drums within which the pea vines are lifted and dropped upon rapidly rotating beaters which open the pods by impact, and the peas thus liberated pass through perforations in the walls of the separating drum and fall onto an inclined separating apron therebeneath. The peas, however7 are thrown in all directions and are frequently crushed by the moving parts which support and drive the drum. The loss is not confined to the peas crushed in this manner for the crushed peas quickly sour, and, when finally dislodged and collected with the other peas, serve to contaminate them. A single bruised pea or even a small particle that has started to ferment will serve to spoil the entire contents of a can or larger container.

The present invention provides means for preventing this loss.

YV ith the above and other objects in view the invention consists of the green pea viner as herein claimed and all equivalents.

Referring to the accompanying drawing in which like characters of reference indicate the same parts in the different views:

Fig. 1 is a sectional view showing the interior of the feed end of a green pea viner constructed in accordance with this invention, the beater drum and the sieve frames of the separating drum having been removed; and,

F ig. 2 is a sectional plan view on the line 2-2 thereof.

1n these drawings 10 indicates a frame on the corner uprights of which are mounted supporting rollers 11 and 12. These rollers support the end rings 13 of a separating drum. The two end rings 13 are connected by lifting ribs 14 and the latter support screen frames 15 to constitute the walls of the drum. The wooden end rings 13 are provided with flanged metal track rings 16 to bear on the flanged supporting rollers 11 and 12 and also with metal sprocket rings 17 having teeth engaged by chains 18 by which the separating drum is driven from a countei-shaft 19. The beater drum 20 is journaled in bearings 21 on cross pieces of the frame.

Beneath the separating drum is an inclined separating apron 22 with inclined guards 23 covering its edges7 the function of the apron being to separate the chaff from the peas when they fall through the perforations of the walls of the separating drum.

The frame is almost entirely enclosed by a roofing 24, side panels 25, end walls 26 and a hanging curtain 27.

A disk 28 on the end of the beater drum 20 lits within a circular opening 29 in the end wall 26 at the feed end of the machine to complete the closure thereof, and an opening 30 in said end wall beneath the opening 29, constitutes a feed opening through which the vines are fed to the viner.

The bent flange of the track ring 16 [its around a bent ring 31 which is secured to the end wall 26 to prevent the peas liberated within the drum from finding their Wa through the space between the end of the drum and the end wall 26. A partition 32, fitted to the ring13 and preferably formed in sections, is placed across the end of the housing and spaced a sufficient distance from the end wall 26 to include the driving and supporting' mechanism for the separating drum, and at its outer edges it is connected with the end wall 26 by means of walls 33. The wall 33 near the upper end of the inclined separating apron 22 has a door 34 hinged to it and adapted to swing from a position in which it forms an extension of the partition 32 to a position over the separating apron. rl'his door serves to cover the supporting roller 12 and when swung open lgives access thereto, but it is normally held in its closed position by a turn button 35. On the other side of the machine a door 36 is hinged to the upright of the frame and when closed forms an extension of the wall 33 and is normally held in that position by a turn button 37 but may be swung open, as shown in Fig. 2 to give access to the supporting rollers 11. When it is closed the curtain 27 hangs against it to form an overlapping connection therewith that will prevent the peas from being thrown out around the edges of the curtain,

The partition and the end wall together with the walls 33, roof 24 and doors 34? and tight'l connection with the curtain for preventing the escape of peas. The rollers 11 dnotrrequire the special protection that is given to the roller 12 as they are farther away from the separating apron and peas will," not rebound from the apron or its guards 23 to lodge thereon.

Whatl claim as new and desire to secure by Letters Patent is: `1.111 a. green pea viner havin@ a separating drum with end 4rings anc screens and means engaging the end rings for supporting and rotating it, a guard for preventing the peas from being crushed by the supportingl and rotating means consisting of a partition extending across the viner and tted to an end ring of the separating drum between the engaged parts thereof and the screens.

2. In a green pea viner having a separating drum with end rings and screens and means engaging the end rings for supporting and rotating it, a guard for preventing the peas being crushed by the supporting and rotating means comprising an end wall, an annular flange thereon fitting withV an end ring of the separating drum, and a partition extending across the viner and spaced from the end wall and iitting the end ring between the means-engaged parts thereof and said screens. Y

3. In a green pea viner, a frame, drum supporting rollers mounted on the uprights ofthe frame, a separating screen drum having end rings mounted on the rollers, driving chains passing around the rings and engaging'therewith for turning the drum, and means for preventing peas being crushed by the rollers and the chains comprising a partition extending across the frame and tting the rings between the screens and the chains and rollers, and'doors hinged tothe frame and also fitting the rings in extension of the partitions and adapted to expose the rollers when opened.

In a green pea viner, a frame, drum supporting rollers lmounted on theuprights thereof, a separating drum having end rings mounted on the rollers, drivingchains passing around the end rings and engaging `therewith for turning the separating drum,

anl inclined separating apron fextending across the frame beneath the separating drurn, and meansrfor preventing the crushing of peas by the rollers and chains comprising partitions extending acrossV the frame and fitting the end rings between the drum screens and the rollers andchains and swinging doors covering the rollers near the upper end of" the separating apron and adapted to expose said rollers when opened.

5. In a green peaviner, a frame, supporting rollers on the uprights thereof, a separating drum having end rings mounted on the rollers, a countershaft, chains passing around the countershaft and around the end rings for driving the separating drum, an inclined separating apron extending across the frame beneath the separating drum, and means for confining the peas to` the space beneath the separating drum comprising partitions extending across the frame and fitting with the end rings between the drum screens and the rollers and chains, doors covering the supporting rollers near the upper end of the separating apron, doors on the other side of the frame extending from the partition to the separating apron, anda curtain hanging against the last mentioned doors.

6. In a green pea viner, a frame, supporting rollers on the uprightsthereof, a separating drum having end rings mounted on the rollers, driving chains engaging the rings for turning the drum, an inclined separating apron extending across the frame beneath the separating drum, and means'for confining peas tothe space beneath the drum comprising partitions extending across the frame and fitting the end rings between the drum screens andthe rollers and chains, doors on one side-of the frame extending from the partitions to the separating apron,

and a curtain hanging against said doors.

7. In a green pea viner havinga separating drum with screens and end rings and means engaging the end rings for supporting and rotating it, a guard forV preventing the peas from being crushed by the supporting and rotating means, consisting of apartition extending across the viner between the screens and the supporting and rotating means.

8. In a green pea viner, a frame, a suitably driven separating drum mounted therein, a curtain suspended from the frame for enclosing the drum, and a wall on the frame against which the curtain hangs in overlapping relation to prevent the peas from being thrown out around the edgesrof the curtain. v j
